BOX-COVER MACHINE.

SPECIFICATION forming part of Letters Patent No. 567,094, datedSeptember 1, 1896.

Application filed May 1, 1896. Serial No. 589,855. .(No model.)

To all whom it may concern.-

Beit known that I, BYRON MORTIMER GUN STON, of Oswego, in the county ofOswego, in the State of- New York, have invented new and usefulImprovements in Box-(lover Machines, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to machines for rabbeting the sides or edges andend of box-covers, and at the same time cutting a recess in the otherend to aid in removing said cover, the rabbeted edges and end of whichfit into corresponding grooves in the sides and one end of the box.

My object is to produce a machine in which the edges and one end of abox-cover are rabbeted and the recess out near the other end, allsubstantially simultaneously. It comprises a hopper receiving thecover-blanks, a feed mechanism by which said blanks are fed out one 'ata time, a rotating cutter upon a traversing frame by which a rabbet iscut across one end of said blank, a boring-head upon avertically-reciprocated shaft by which a recess is out part way throughsaid cover near its outer end, stationary saws parallel to each otherand spaced apart according to the width of said blank, and by whichrabbe ts are cut in the edges as they are fed through a channel having astationary side and a spring-pressed side, and also having a springpressed top to hold said blanks in proper relation to the rabbet-cuttersand borer, means being provided to adjust the rabbet-saws vertically andlaterally to take up wear and to covers of different widths orthicknesses. It is constructed as follows, reference being had to theaccompanying drawings, in which- Figure 1 is a front elevation of themachine. Fig. 2 is a rear elevation thereof. Fig. 3 is a verticaltransverse sectional elevation of the same. Fig. 4tis atop plan. Fig. 5is a detail of the blank-feeder. Fig. 6 is an elevation of a saw and themeans for its adjustment. Fig. 7 is a plan of the saw-frame. Fig. 8 isan edge view thereof. Fig. 9 is an elevation of the saw-frame holder andadjustingscrews. Fig. 10 is a vertical section thereof. 11 shows at a atop plan of a be tilted to afford better access to the rabbctcutters andthe borer.

Upon the table a cover blank hopper m is erected, comprising a verticalside 6 and a like end 7, erected upon a slide 8, adjustable by means ofthe set-screws 9, and dovetailed or other ways 10, and also comprisingapost 11, secured to the end 7 ,substantially in line with the bar 12,which is a side of the blankconduit, and to this post 11 is hinged aside piece 13 to which is secured an end 14., and 15 is a handle bywhich the. parts 13 and 14 are swung around to open the hopper, andwhich when swung back holds the cover-blanks therein with their sidesand ends in vertical alinement. In this table a slot 16 is cut in whicha slide 17 is mounted, upon which the feed-dog 18 is pivoted.

The main drive-shaft 10 is suitably journaled in the frame and driven bythe belt 20, and 21 is a pulley on said shaft driving the belt 23 andpulley 22 on the shaft 25, thus driving the pinion 26 on said shaft andthe gear 27 on the shaft 28, which rotates the crank-disk 29, whichreciprocates the adjustable pitman 30, and this oscillates the lever 31,pivoted at 32 and connected by the link 33 to said feed-dog slide, andthus reciprocates the latter and with each forward movement feeds acover-blank into the conduit 34, of which the slide 8 constitutes oneside, the bar 12 the other side, against which the springs 37 bear tohold the cover-blank firmly against the slide 8. This conduit isprovided with a top or cover 36, against which the springs 35 bear,their tension being regulated by the screws 38, throughv the arches 39,mounted upon the table, and said top is guided vertically by a suitableguide or guides 40, extending up through said arches. The feed-dogpushes the blank into said conduit, leaving it in proper position tohave one end rabbeted and the other recessed.

Upon the shaft 28, and driven by it, a crank- IOO disk ll is secured,actuating a pitman-rod 42, connected to an arm 43, secured to therockshaft atlto rock said shaft and vibrate a lever secured to it, andthereby through a link -16 reciprocate a frame 47, mounted in a way orways l8 upon the main frame. This frame consists of a base and twouprights thereon in which the cutter-shaft 49 is journaled, and 50 isthe end-rabbeting cutter secured upon said shaft, all so that saidcutter is rcciprocated in a suitable slot (not shown) in the table, andin a direct line, being guided by said ways.

Upon the shaft 19 a pulley 51 is secured, and 52 is a belt driven by it,passing under the tightener-idlers upon the swinging bar 54: and aroundthe pulley 55 upon the cuttershaft. This rabbets the end of the blank. Apulley 56 upon the shaft 19 drives the belt 57, guided by the idler 58,the pulley 59, the shaft 60, to which it is secured, and upon which asuitable borerGl is secured. This is normally out of contact with theblank. It is adapted to be reciprocated through a suitable opening inthe table by the following mechanism.

Upon the disk 29 a pin 62 is secured, adapted to intermittently engagewith a lever 63, pivoted at 64 and suitably connected to the borershaft,so that while in such engagement the cutter is raised to bore a recesspart way through the blank. This recess is used to aid in removing thecover from a box.

When the end rabbet has been cut, the cutter is at one side, and whenthe borer has cut a recess it is retracted, (or falls of its ownweight,) and both are out of the path of' the next blank, which whenfedin pushes the preceding one along in the channel for the edgerabbeting. A pulley 65 upon the shaft 19, a belt 06, and pulley 67 uponthe saw-arbor 68 drive the rabbeting-saw 69 on one side of the machine,and a like mechanism drives a like saw 011 the other side, so that bothedges of the blank are rabbeted simultaneously, as it is pushed along bythe feeding in of the succeeding blanks, and finally discharged from thetail of the machine.

The saw-arbors are each journaled in avertically and laterally movableslide 70, and each saw is vertically adjusted and set to make anydesired depth of rabbet cut by means of a set-screw 71, and to vary thewidth of the cutby the set-screw 7 2. The set-screw 71 is also used totake up the wear of the saw, or its reduction in radius incident to itsuse, filing, &c. A lever 73, suitably pivoted at or starting anddesire 1. In a box-cover machine, a conduit, a hopper, and means to feedthe cover-blanks therefrom singly into said conduit in combination witha rotating cutter mounted in a traversing frame and means to rotate saidcutter and traverse said frame across said conduit to cut a rabbetacross one end of a cover-blank.

2. In a box-cover machine, a hopper, a conduit, and means to feed thecover-blanks into said conduit singly in combination with a disk havinga crank-pin, a crank-rod connected to it, a rock-shaft, a rock-armsecured to it and connected to said crank-rod, a vibratory arm securedto and actuated by said rockshaft, a rotating cutter mounted in a frame,and a link connecting said frame to said vibratory arm, whereby saidframe is reciprocated transversely to said conduit causing said cutterto rabbet the end of a cover-blank.

3. In a box-cover machine, a hopper, a conduit, and means to feed thecover-blanks into it singly, in combination with a rotating diskhavingastud in its face, a rocking lever with which said studintermittently engages, a vertical boring shaft with which said leverengages to reciprocate it vertically and recess the cover-blank, andmeans to rotate said disk and shaft.

4:. In a boX-cover machine, a hopper, a conduit, and means to feed thecover-blanks into it singly, in combination with a rotating disk havinga crank-pin in one face, and a stud in the other face, a crank-rodconnected to said crank-pin, a rock-shaft, a rock-arm secured to it andconnected to said crank-rod, a vibratory arm, secured to saidrock-shaft, a rotating cutter mounted in a frame, and a link connectingsaid frame to said vibratory arm, a rocking lever with which said studintermittently engages and a vertical boring shaft with which said leverengages to reciprocate it vertically, whereby one end of the cover-blankis recessed and the other is transversely rabbeted.

5. In a box-cover machine, a hopper, and a conduit receivingcover-blanks therefrom, in combination with a rotating cutter traversingacross said conduit whereby one end of each blank is transverselyrabbeted, a vertically-reciprocating borer whereby an end of each blankis recessed, and rotating saws on opposite sides of said conduit wherebythe edges of each blank are longitudinally rabbeted.

I11 witness whereof I have hereunto sctmy hand this 29th day of April,1896.
